various endian fixes to cifs

make modules C=2 M=fs/cifs CF=-D__CHECK_ENDIAN__

Found for example:

In checking new smb2 code for missing endian conversions, I noticed
some endian errors had crept in over the last few releases into the
cifs code (symlink, ntlmssp, posix lock, and also a less problematic warning
in fscache).  A followon patch will address a few smb2 endian
problems.
